Answer: $247.50
Step-by-step explanation:
10 * 50 = 500
500 + 400 + 2100 = 3000
8.25/100 = 0.0825
3000 * 0.0825 = 247.5
5x-4=-2(3x+2)
5x-4= -6x-4
5x+6x= -4+4
11x=0
X=0/11
The answer is <span> B- y=4-1.5x
</span><span>David is rowing a boat upstream, so the river is slowing him down. Thus, the net speed is 6 mph - 2 mph = 4 mph.
Since David's speed </span><span>decreases at a rate of 1.5 miles per hour, after x hours his speed y will be:
y = 4 - 1.5 x</span>
